Central AC installation by home size: Gresham vs Lake Oswego

| Size | Gresham | Lake Oswego |
|---|---|---|
| 1,000 sq ft (≈2 tons) | $5,100–$8,850 | $5,100–$8,850 |
| 1,500 sq ft (≈2.5 tons) | $5,600–$10,450 | $5,600–$10,450 |
| 2,000 sq ft (≈3 tons) | $6,150–$12,050 | $6,150–$12,050 |
| 2,500 sq ft (≈4 tons) | $7,750–$14,200 | $7,750–$14,200 |
| 3,000+ sq ft (≈5 tons) | $9,350–$17,400 | $9,350–$17,400 |

Cheapest time for central AC installation in either city
Demand for HVAC work falls off a cliff in the shoulder months, and contractors discount to keep their crews booked. Wait for a 100-degree day or a hard freeze, though, and you're paying emergency rates for a system that just quit.
How much should you really budget for HVAC in 2026?
Ask five contractors for an HVAC quote and you'll get five different numbers — usually because they disagree on sizing, efficiency and equipment tier. Here's how our editors think through those trade-offs.
The longevity case
Brand is a footnote; sizing and install quality write the story. A right-sized mid-tier system that's properly commissioned and serviced once a year will outlive an oversized premium unit that short-cycles itself to an early grave. Put the money into the crew and the setup rather than the nameplate.
The efficiency-first case
High runtime changes the math. In a demanding climate the extra efficiency of a heat pump or a top-tier SEER2/AFUE unit gets paid back month after month on the utility bill, and state and utility incentives can shave the upfront figure further now that the federal 25C/25D credits have expired. Price the lifetime bills, not just the tag, before you default down.
The budget-first case
Run a Manual J load calculation, then buy the standard tier — 80% AFUE, 14.3 SEER2 — and stop there. Where summers are short and winters are gentle, the equipment idles most of the year, so premium efficiency never gets enough runtime to earn back its price. Paying for SEER2 you'll rarely tap is the classic way a mild-climate homeowner overspends.
The brand on the unit matters far less than getting the sizing and installation right. Insist on a Manual J calculation, match efficiency to your climate, and claim every rebate available.
